Mogu'shan Palace Heroic Dungeon Guide (WoD 6.1)

The Mogu'shan Palace is a 5-man dungeon located in the Valde of Eternal Blossoms
on Pandaria. The Normal-difficulty version of the dungeon is open to players
between level 87 and 90, while the Heroic-difficulty version of the dungeon is
reserved to level 90 players. It houses 3 encounters:
Trial of the King, Gekkan, and
Xin the Weaponmaster.

The Mogu'shan Palace becomes available to players after reaching level 87.
In this dungeon, players need to defeat this last
bastion of the Mogu, further weakening their positions on Pandaria.

The dungeon has a linear layout during which you will progress through
four different zones and encounter three bosses. The dungeon features
both Normal (level 87+) and Heroic (level 90) modes. There are no
differences in mechanics between Normal and Heroic modes. The only
differences are increased health and damage done for all bosses and enemies.

This guide will cover all of the three boss encounters, as well as the
quests and achievements that are available in the dungeon.

6.2.1. Haiyan the Unstoppable

For this fight, players need to stack loosely to deal with
Meteor. They need to be spread out no more than 10 yards.
When Haiyan casts this ability (something he does regularly), it will send a
meteor at a random party member, dealing damage shared by everyone within 10
yards of the impact.

Other than that, random players will often be afflicted by
Conflagrate, which deals Fire damage for 5 seconds
and disorients. When Conflagrate ends, it jumps to a nearby player.
To prevent this from happening, move away from players afflicted by
this ability.

Healers should pay special attention to Haiyan's last ability: Traumatic Blow.
It causes the tank to receive 50% less healing for 5 seconds.

After defeating the Trial of the King, you need to follow a Saurok down a
flight of stairs that will open up on the side of the arena. After fighting
a few groups of trash mobs, you will meet Gekkan and his four followers:
Glintrok Hexxer, Glintrok Ironhide, Glintrok Oracle, and
Glintrok Skulker. To progress past this encounter, you need to defeat
all 5 enemies, even if you kill Gekkan first.

7.1. Abilities

Gekkan, the Glintrok Ironhide, and the Glintrok Skulker will attack players
with melee attacks, so they need to be tanked. The Glintrok Hexxer and the
Glintrok Oracle will remain stationary for the entire duration of the fight.

Gekkan will often buff his followers with Reckless Inspiration, which
increases their haste and the damage that they take. This effect can stack up
to 10 stacks. Reckless Inspiration is Gekkan's only ability. Upon dying,
he will stack Reckless Inspiration one last time on all his remaining followers.

Gekkan's followers have various abilities. All of them are interruptible.

The Glintrok Oracle casts Cleansing Flame, which
regularly heals all allies within 60 yards for a large amount, and
Fire Bolt (only if no one is in his melee range),
which deals Fire damage.

The Glintrok Hexxer casts Hex of Lethargy, which inflicts shadow
damage and applies a stacking debuff on the target that reduces spell casting
speed, and Dark Bolt (only if no one is in his melee range), which
deals Shadow damage.

7.2. Strategy

Despite the large number of combined abilities from the boss
and his followers, the combat is relatively simple.

The most important part of the encounter is to focus on
interrupting the abilities of the followers. While the
Glintrok Ironhide and the Glintrok Hexxer are still alive,
interrupt their abilities with priority.

With that in mind, we believe that the easiest strategy for this
encounter is to kill the followers in the order we give below before
killing Gekkan.

Kill the Glintrok Ironhide, so that you no longer need to interrupt
his channels of Iron Protector.

Kill the Glintrok Hexxer, so that you no longer need to interrupt
his casts of Hex of Lethargy.

Kill the Glintrok Skulker.

Kill the Glintrok Oracle.

Once all the followers are dead, the tank and the healers must be mindful
of the fact that Gekkan will have 4 stacks of Reckless Inspiration,
which cause him to attack twice faster.

7.3. Achievement: Glintrok N' Roll

Completing Glintrok N' Roll is very straightforward, although it is not
an easy task, especially since you need to do it in the Heroic version of the fight.

When you enter the lower part of the palace, a Glintrok Scout will spot you
and you will be given a very visible emote. From there on, you have 5 minutes
to kill Gekkan and his followers.

There are a lot of trash mobs on your way to Gekkan, so you cannot
realistically engage them all and still make it in time (at least
not at low gear levels). To skip fighting as many mobs as possible, you should
jump down into the arena where you fight Gekkan, as soon as your reach
the room where this arena is located.

Xin the Weaponmaster is the last boss of the dungeon and will
present you with an interesting fight, during which there are no
complex mechanics to deal with. Rather, you will have to be almost
constantly on the move to avoid the various traps and damaging
abilities that the boss will throw at your group.

Inciting Roar and Death From Above! are the only
source of unavoidable damage in the fight. Inciting Roar is regularly cast by
Xin. Death From Above is not a spell or an ability, but rather it is
an event that actives when Xin reaches 33% health. It causes damaging arrows to
be shot to players from the walls.

The other sources of damage can all be avoided by properly moving out of the
danger zone they create.

Ground Slam deals damage in a 30-yard cone in front of Xin and
stacks an armor reduction debuff on players hit by the slam. Avoid standing
in front of Xin.

Circles of Flames will be created throughout the fight around random
players. The circle takes a few seconds to complete, after which time it explodes
and deals damage to players inside it, knocking them into the air. Move out
of circles of flames being drawn around you.

Whirlwinding Axes are axes that travel through the arena and deal
damage to players they run into, knocking them back in the process.

Blade Trap activates when Xin reaches 66% health and causes streams of
swords to be thrown at the party from the walls, dealing heavy damage to anyone
they catch.

Circles of Flames and Whirlwinding Axes are the most important abilities.
If you are caught by them, you will knocked back or into the air, which runs the risk
that you will land on another zone of danger.

When Xin reaches 33% health, all the traps are activated and the arena becomes very
confusing, and you will have very little room to move. There is no known enrage
timer to the encounter, so you should focus on avoiding abilities and attack
the boss when you are safe.

8.2. Achievement: What Does This Button Do?

Shortly after Xin activates his Death From Above! trap, you will
see 2 crystals appearing on opposite corners of the room. You will need to designate
two players whose task will be to reach these crystals and click them. As a result,
another crystal will appear along the walls of the room. This new crystal represent
the secret defense mechanism mentioned in the tooltip of the achievement. Clicking
it will activate that secret weapon and you simply need the tank to move the boss
in its path.

Note that with all players spread around the room, healing them will be somewhat
chaotic. To make it easier, the healer should try to remain close to the center of
the room, so that everyone in the party is in range (or almost in range).

Quarrelsome Quilen Quintet is a very straightforward achievement. To
complete it, you need to collect the 5 Jade Quilens hidden inside
the dungeon. These are small, friendly NPCs with a very distinctive green
color.
